An effective and long-lasting power supply is the backbone of any IoT device. Switch-mode power supplies (SMPSs) are undoubtedly good for powering IoT devices, but most of them are bulky and expensive ...

You may have seen the Ruideng range of programmable power supply modules from China: small and relatively inexpensive switch-mode buck converters, with microprocessor control and a front panel ...

Editor’s note: In Part one, we looked at an intro and the basics of linear regulator and switching power supply operation. This final part two will look at design considerations of the switching power ...

Today, 80% of all input/output (I/O) devices in automation applications are supplied with 24VDC power. The second most popular voltage is 120VAC, which is used on 15% of all I/Os. Over the past decade ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

If you want to easily control the power in a circuit, you’ll probably reach for the classic toggle switch. While there’s certainly nothing wrong with that, physical toggles are a bit dated at this ...

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...

An industry expert addresses the debate of discrete components vs. external boxed filters for suppressing noise. The analysis and suppression of electro-magnetic interference (EMI) generated from high ...

Input ratings: Typical power-supply modules are designed and rated to operate with their inputs connected to lines delivering 105 to 125 Vac. Input ratings: Typical power-supply modules are designed ...

The most important thing to keep in mind when operating the server yourself is the power supply. Even if applications and networks are running normally, it does not make sense to power down essential ...
